SPECIFICATION forming part of Letters Patent No. 354,280, dated December 14,1886,

Application filed May 10. 1886 Serial No. 201,099. (No model.)

To aZZ whom it may concern..-

Be it known that I, RUDOLPH \Vniss, a citizen of Switzerland, residing at Nottingham, England, have invented a new and useful Machine for Removing Bobbins from Carriages of Lace-Machines, lnsertingthem Therein, and Threading the Carriages, which invention is fully set forth in the following specification.

This invention relates more particularly to machinery for automatically removing the empty bobbins from the carriages of lace (bobbinet) machines, supplying full bobbins, and threading the carriages with the thread on the full bobbins by a series of consecutive operations, but it is or may be applied, at least in part, to machinery for performing separately one or more of these operations, or for other purposes.

The invention consists, first, in a traveling holder or holders for the carriages, which will carry the carriages to or over suitable devices and permit a bobbin to be removed by the ac tion of said devices from a carriage or inserted into the same, or to be removed and replaced by another while the carriage is retained in the holder.

Theinvention consists, secondly,in a retract 01' provided with a pin for insert-ion behind the carriage-spring and mechanism whereby said retractor is actuated to lift the spring on the carriage away from the bobbin so that it does not interfere with the removal of the bobbin; also, in the combination, with atraveling carriage holder or holders, of a bobbin lifter or lifters for pressing the top of the bobbin be yond the carriage so that it can be slipped out, and an extractor for withdrawing the bobbin from the carriage. These appliances are operated by appropriate mechanical, means, such, for example, as cams and connections.

The invention consists, thirdly, in the combi nation, with a traveling QarriagehOlder, or a series of such holders, of the following appliances for eifecting or assisting in the insertion of thebobbins, namely: bobbin-holdingmechanism for supporting the bobbin in proper relation to the carriage so that by an edgewise motion it can be slipped into the carriage; a bobbin-inserter or bobbin-inserting mechanism for giving the requisite edgewise motion to the bobbin, and a carriage-spri ng replacer, or means for applying the carriage-spring to the bobbin. Practically the same devices which retract the spring for removing a bobbin are or may be employed to restore the spring when a bobbin is inserted.

Theinvention consists, fourthly, in the combination, with the traveling carriage-holder, or a series of such holders, of means for delivering bobbins as they are required for insertion in the carriages or bobbin-delivery mechanism.

The invention consists, fifthly, in tension appliances, consisting of a belt, movable step by step, and ahorn, between which the threads may be placed for holding the threads from full bobbins so as to prevent their becoming parts of the machine, such as the brush.

The invention consists, sixthly,in the combi nation, with a traveling carriage-holder, or a series of such holders, of means for threading the carriages, or carriagethreading mechanism. Practically a hook, traveling with the carriage-holder, or with each of a series of such holders, for drawing the thread through the eye or thread guide on the carriage, and a thread-carrier for placing the thread in the hook, are used for the purpose, said hook and thread-carrier being operated by suitable mechanical means, such, for example, as cams and connections.

The invention consists, scventhly,in the combination, with a traveling carriageholder, or

aseries of such holders, of carriage-delivery mechanism, or means for delivering carriages to the carriage-holders.

The invention consists, cighthly, in the combination, with a traveling carriageholder, or a series of such holders, of means for removing the carriages from the holders or carriageremoving mechanism.

The invention further comprises the combi nation, with each other, of two or more of the before-mentioned means, mechanisms, or appliances, and also certain special constructions, combinations, and arrangements of parts, as hereinafter set forth.

It is designed to unite in one machine all the parts, improvements, and combinations entangled with one another or with certain included within the invention; but it is evident that this is not essential, some parts of the invention being susceptible of use separately.

The following is a description of what is considered the best mode of applying the principle of the invention, reference being had to the accompanying drawings, which form a part of this specification.

Figure 1 is a perspective front view of a machine constructed in accordance with the illvention; Fig. 2, a plan view of the same; Figs.

3 and 5, views in horizontal section on different planes; Fig. 4:, a partial view in horizontal section; Fig. 6, an end elevation, and Figs. 7 to 11 partial views in vertical section on different planes.

Like letters and reference-number-s indicate like parts on all the figures.

A movable bed, A, shown in the form of a horizontal revolving disk, is mounted upon and turns with an upright shaft, B. It is provided with recesses -D, of a form and depth adapted each to receive a carriage, E, flush with the upper surface of the bed.

The machine-frame is composed of the plate F, the legs and cross-pieces which support it, the top plate, G, and the pillars H H H bolted to the plate F and supporting the top plate, G. The shaft B is journaled in bearings on the plates F G, and is revolved by a belt on pulley 1 through cross-shaft 2 and bevelgears .3 and 4. The recesses in the bed or disk A are preferably formed by cutting openings of the right shape in a surface-plate, 5, (see Figs. 8 to 11,) of the same thickness as the carriages, as this avoids forming the recesses in the solid metal. The carriage-box is formed, as shown, by the rods 6, fastened at the upper ends to the top plate, G, and at the lower ends to the stationary carriage-holding plates 1 1 These rods are so arranged that they keep the carriages from turning, and that when a pile of carriages is placed in the box or conduit formed by said rods, the bottom carriage will register with each recess in the bed when said recess comes below the mouth of the box. The top plate, G, and the holding plates 1 l are cut away to permit the carriages to be introduced at the top and removed at the bottom of the carriage-box. The holdingplate I is fastened by the bracket 7 to the pillar H and to the plate F by the bracket 8. The holding-plate I is fastened to the plate F, and holding-plate I by bracket 8 to the bobbin-box M by the anglepiece 9, (see Fig. 3,) and to the bridge P by angle-piece 10. (See Fig. 9.) The holding-plate l is itself bent, and has its foot fastened to the plate F. The holding-plates I I I are placed just above the bed or disk A.

A space whose width equals the diameter of the bobbins is left between the inner plate, I, and the outer plates, P 1 When a recess comes under the carriage-box, the bottom carriage enters the recess andis carried along with the bed or disk under the plates I 1 1 which confine the carriages in the recesses. A series of traveling carriage holders is thus formed, the series extending in the direction in which the holders travel. The bobbins not being confined by the holding-plates can be removed or inserted.

A separate spring-retractor is used for each recess or carriage-holder. Each of these retractors is or may be duplicates of the others. As shown, each consists of a lever, 11, (see Fig. 10,) pivoted to the bracket 100 on the under side of the bed or disk A, a bell crank, 15, pivoted to the lever 11, and a pin, 13, at the upper end of the bell crank. This pin works through a slotin the bottom of the re cess, and is provided with a blade or point, so that the upper end may enter easily bet ween the spring and bobbin.

All of the levers 11 are actuated by the stationary can1-ring 14,and allofthe bell-cranks 15 by the stationary cam-ring 16. A spring, 12, tends to force down each lever 11. The cam 14, by raising the lever 11 and allowing it to fall,raises and lowers the pin 13,while the cam 16, by causing the bell-crank 15 to rock onits pivot, gives to the pin a movement lengthwise of the slot. This compound-lever arrangement has been adopted as the most convenient mounting for the retracting device or pin 13-.

The bobbin-lifters for each recess or carriage-holder consist, as shown, of pins 17 and 18, at the ends of levers 19 and 20, respectively, the levers being pivoted to bracket 100 and resting at or near their front ends, the levers 19 upon thestationary cam-ring 21 and the levers 20 upon the cam-ring 22. The pins rise and fall through holes in the bottom of the recess, and when they rise they raise one edge of the bobbin above the carriage, so that it can be slipped out by an edgewise motion.

The bobbin-extractor is, as shown,in the form of a wheel, K, provided,near its periph cry, with a series of depending pins, 23, each pin being combined with a spiral compression-spring, 24, (see Fig. 7,) for forcing it into the eye in the center of the bobbin when the pin is carried over it, and a nut, 25, for limiting the downward motion of the pin. The wheel K is mounted upon and turns with an upright shaft journaled in the bracket 26. It is revolved by the spur-gear 27, fixed on the shaftB,engaging the smallerspur-gear,28,fiXed on the shaft of wheel K. -The gears are of such relative size that the extracting-pins 23 move faster than the bobbins, and are thus enabled to extract the-bobbins from the earriages.

The operation in detail of retracting the spring and extracting the bobbin can now be understood. (See Figs. 5 and 10.) The bobbin-lifters 17 and 18 are first raised by the inclines 29 of cams 2]. and 22 acting upon levers 19 and 20, and immediately thereafter, While the bobbin is still pressed out, the retractorpin 13 is raised by the incline 30 of cam 14 acting upon the lever 11 until said pin touches the bobbin,and it is then advanced by the incline 31 of cam 16 acting upon bell-crank 15 until said pin engages the spring 32 of the car- IIQ riage. The inclines 33 of cams 21 and 22 then allow the bobbin-lifters, and with them the edge of the bobbin, to fall, the end of the pin 12 entering between the bobbin and the spring. The pin 13 is then-further advanced byincline 31 until the spring is fully retracted, as shown in Fig. 4. It may be kept in that position until the empty bobbin has been removed and afnll bobbin inserted. As the bed or disk A continues to revolve, the bobbin-lifters are again raised by the inclines 34 of cams 21 and 29 and press out the bobbin at one edge. At this time the bobbin is under the extractorwheel K, and one of the pins 23 enters the eye in the middle of the bobbin. As this pin moves faster than the carriage, it draws the bobbin out of the carriage, and, dragging it over the stationary platform 35, Fig. 2,whose upper surface is flush with that of the bed or disk A,delivers it into the empty bobbin re ceiver L. The bobbin-lifters are then allowed to descend by inclines 304. The receiver L, as shown, is in the form of a round table provided with a raised rim, and is mounted upon an upright shaft, 36, which is revolved slowly by the belt 37, (see Figs. 5 and 6,) running on the pulleys 38 and 39, the larger one being fast on the shaft 36, the smaller one on the shaft B.

The bobbin-b0X M, in the form of a slotted tube, is suspended from and fastened to the top plate, G, by means of a flange, 40, (see Figs. 1 and 2,) the top plate being cut away to receive it. The endless belt N of the tension apparatus is stretched between the pulley 41, carried by the top plate, and the pulley 42. (see Figs. 3 and 8,) on the holding-plate 1. It is provided with holes or recesses to receive projections 43 (see Fig. 2) on the pulley 41, to prevent slipping. The pulley 41 is fastened to a ratchetwhecl, 44, and is driven by a reciprocating spring pawl, 45, engaging the ratchet-wheel. This pawl is attached to the end of lever 46, which latter is vibrated by the cam 47, fast on shaft 13, pushing it in one direction, and the spring 48 returning it. As shown, the spring is attached to the lever, and is confined between the lever and the stationary pin 49. The bridge P, bolted to the pillar H, is provided at its inner end with the upright horn 50, arranged close to the belt N, so

that the threads inserted between them will be held in place and be carried downward as the belt revolves. \Vhen the full bobbins are placed in bobbin-box M, the ends of the threads are led through the slot in the side of the bobbin-box, and placed in the tension apparatus between the belt N and the horn 50. The brush Q is fast on the shaft B, and turns with the same. It acts upon the ends of the threads and keeps them taut, and thus serves also to prevent tangling.

The movable device It for upholding the pile of bobbins in the bobbin-box is, as shown, in the from of a lever-arm, pivoted to the bracket 51, which in turn is bolted to the pillar A projection, 52, on one side of the leverarm enters a slot in the side of the bobbin-box, and bears against the edges of a number of bobbins. The bearing-surface is faced with leather, rubber, or other soft material. A spring, "53, presses the lever-arm in ward normally, so that it supports the pile of bobbins. At proper times, however, the leverarm is drawn back by the cams or projections 54 (of which there is one to each recess) on the edge of disk A, and the pile of bobbins is allowed to descend. The cams or projections 54 act upon the tail-piece 55 of the lever-arm. The lever-arm It also operates as a brake to prevent the brush Q from unwinding the thread.

At the bottom of'the bobbiirbox is a removable stop, formed, as shown, by the inner end of lever S. This lever is pivoted at the enter end to the pillar H and is raised at the proper times to allow a bobbin to pass out by the cams or projections 56, of which there is one to each recess. These cams 56, as well as those numbered 57 and 58, (whose function is to control a portion of the bobbin-holding mechanism, hereinafter described,) are placed on the top of a flat rim or annular extension, 59, of the disk A. They pass under the platform 35, and also under another platform, 115, whose function is explained below. The lower part of the bobbin-box M is cut away on one side, as shown at 60, Fig. 8, so that the bottom bobbin can be slipped out, provided the lever S is raised at the time. The spiral tension'spring 61 assists in holding down the lever, and a setscrew, 62, limits its downward motion. For each carriage holder or recess (see Fig. 11) there is a pin, T, which plays through a boss, 63, on or near the end of lever U, which is carried by the bed or disk A, and projects through a slot in the bottom of the recess. The lower ends of the pins T rest upon the stationary cam-ring 64. \Vhen a recess in the bed A comes under the bobbin-box, the pin T is raised by the incline 65, and its upper end enters the eye in the bobbin at the bottom of the pile. The stop-lcver S being raised at this time, the bobbin is carried out of the box by the pin T.

Immediately before the pin T is raised the pins 66 and 67 or bobbin-levelers are lifted so as to bear upon the under surface of the bobbin and keep it level. Theseleveling-pins (of which there are two to each recess) are mounted upon levers 68 and 69, respectively, which levers are pivoted to the bracket 100. The outer ends oflevers 68 rest upon the stationary ring 70; those of levers 69 upon the stationary cam-ring 71. They are raised just in advance of pin T by'the inclines 72.

Each of the pins T forms a bobbin-inserter, it being given a lateral motion for inserting the bobbin by means of the stationary or bracket cam 73, which acts upon the bell-crank 74, and through the latter upon the lever U. (See Fig. 4.) The bell-crank 74 is pivoted to the bed or disk A, and is provided with a spring, 75, for acting upon thelever U, so that if the motion of the pin T should be resisted the spring will yield and breakage be thus avoided. A spiral tension-spring, 181, returnsthe lever U when the insertion is eompleted. Before, however, the bobbin can be inserted it must first be adjusted, so that the ends of the semicircular verge 76 are opposite the space between the sides of the bobbin. This adjustment is effected by the bobbin-holding mechanism, which, as shown, consists partly of the movable bobbin-supporters on the bed or disk Anamely, the bobbin-lifters 17 and 18 and the bobbin-levelers (36 and 67 and partly of the bobbin-holder carried by the stationary frame of the machine and consisting of the lever-arms 77 and 78, each of which is provided with a bearingroller, 79. These arms are fastened to the inner ends of short rock-shafts and 81,journaled in brackets which depend from the bridge P.

At the outer ends of the rock-shaft are elastic arms 82 and 83, which are acted upon by cams or projections 57 and 58 whenever a recess is under the bearing-rollers 79, to cause said rollers to press upon the bobbin. The rock-shafts are or may be combined each with a retracting-spring, 85. (See Fig. 9.) The bobbin-lifters 17 and 18 are raised by the inclines 86, and the bobbin-levelers 66 and 67 are allowed to fall by the inclines 87, while at the same time the bobbin is clamped by the bearing-rollers 79, so that the bobbin is held with the space between the sides of the bobbin opposite and on a level with the ends of the verge 76. At this time the lever U and insertion-pin T are given the lateral motion for pushing the bobbin into the carriage. As the insertion proceeds, the bobbin-lifters are carried over the inclines 806 and descend, the pressure of the clampingarm 77 is dimin- 'ished,and that of the arm 68 increased, so that the bobbin becomes more nearly horizontal as the insertion proceeds. The bottom of the re cesses in the bed or disk A is inclined, as

shown at 84, Fig.11, so that the bobbin can be adjusted properly for insertion.

The thread-earrier consists, as shown, of a pin, 0, mounted upon an arm of a vertical rock-shaft, 88, which is journaled in bearings of the bridge P, and is turned in one direction by the projections 89 (one for each recess) 011 the bed or disk A, and in the other by the spring 90. A bell-crank, 91, pivoted to a bracket on the pillar H is acted upon by the projections and draws down upon the chai n 92, which runs over the pulley 93 on bridge P, and is wrapped partly around a hub on the rockshaft 88, so as to turn the thread-carrier to the left. The spring draws upon the chain 94., which is wrapped in the opposite direction around the said hub, and turns the thread-earrier to the right whenever the projections 89 release the bell-crank 91. The pin G enters the curved groove 185 in the holding-plate I when it is turned, and as it moves to the left it engages the thread (stretched between the bobbin and the tension apparatus) and lays it in a threadinghook, 95. Each of these hooks (of which there is one to each recess) is mounted on a carrier, 96, guided by a hole in the bed or disk A, and connected with the operating-lever 97, which latter is pivoted to the bracket at one end, and at the other end rests upon the stationary camring 98. During the inserting operation, as soon as the bobbin has uncovered the thread-eye 99 in the carriage, (see Fig. 11,) the incline 101 acts upon the lever 97 and thrusts the hook upward through the eye. Vihen itis raised, the thread-carrier introduces thev thread, and the incline 102 allows the hook immediately to descend and draw the looped thread through the eye 99. )Vhen the insertion of the bobbin is complete, the incline 103 allows the insertionpiu T to descend. The carriage, with the inserted bobbin; is carried by the revolution of the bed or disk A under the roller 104, mounted and turning upon a stud fixed to a stationary bracket, 105. At this time the inclines 106 and .edge of abobbin, its nib 108 (see Figs. 3 and 4) entering between the sides of the bobbin. The

.hook 109 prevents the thread from getting under the roller 10L Each recess is provided with a carriageejector, 110, mounted upon alever, .111, which is pivoted to a bracket, 100, and at the outer end rests upon the stationary cam-ring 112. The ejector works through a hole in the bot tom of the recess under the front part of the carriage. The ejector is raised by the incline 113, and while raised the carriage is removed by the wheel W. It is or may be constructed and operated substantially as the bobbinextractor wheel K, and therefore needs no further description. the eye in the bobbin and the rotation of wheel \V draws the carriage from the recess, drags it over the stationary platform 115, onto the chute 116, down which the carriage slides to the endless belt X. As the carriage is removed from the bed or disk A, the looped thread is held by the hook 95, and the end of the thread is therefore drawn completely through. the eye. As or before the carriage enters the chute 116 one edge passes under the roller 117 and is held back by it, so as to turn the carriage into the position shown in Fig. 2, with the thread-eye turned toward the bed or disk A. After the carriage has been removed, the ejector is allowed to descend by the incline 118, so that it does not interfere with the entry of a new carriage into the recess when the latter passes under the carriage-box.

The endless belt X is stretched on rollers 119, and revolved at intervals by a reciprocating pawl, 120, engaging a ratchet-wheel, 121, on the shaft of one of the rollers. The pawl 120 is connected with the outer end of lever 122, (see Fig. 5,) pivoted to the plate F. The pawl is moved in one direction by the pin 123 on the gear 124, (which operates the wheel) and is returned by the spring 125. The upper One of the pins 114 enters portion of the belt travels over a bed and serves as a carriage-receiver. \Vhen a number of carriages have collected on the belt, they are removed by the attendant.

The operation of the machine will be under-* stood from the foregoing description, but a brief explanation of the operation as a whole, in the succession in which the different steps are or may be performed, may be useful.

The earriage box 6 is supplied with carriages containing empty bobbins, the bobbinbox M with full bobbins, the ends of the threads being held by the tension apparatus N 50. Starting from a point where a recess, D, is under the carriagebox 6, and a carriage has dropped into it, the revolution of the bed or disk A through an angle of thirty-five degrees (35) brings the carriage well under the holdingplates 1 I, which confine the carriage in the recess. The bobbin-lifters 17 and 18 then rise and press the edge of the bobbin beyond the carriage, and at thirty-eight degrees (38) the spring-retractor is lifted until the pin 13 touches, or nearly touches, the lower surface of the bobbin. From thirty-eight degrees (38) to fortyfive degrees(45) the retractor'pin 13 advances to the periphery of the bobbi n,whereupon the bobbin-lifters 17 and 18 fall and the blade of the retractor-pin 13 enters between the carriage-spring 32 and the bobbin. The retraetor is then further advanced until the bed or disk A has turned through fifty degrees, (50) by which time the spring 32 is fully retracted. During the next thirty-five degrees (35) of revolution the parts remain as before, except that the carriage has passed from under the plate I", and is now held by the plates 1 and 1 At eighty-five degrees the bobbin-lifters 17 and 18 again rise, and at ninety degrees one of the pins of extractor-wheel K enters the eye of the bobbin, and during the next four degrees, draws out the empty bobbin and delivers it into the receiver L. At ninety-five degrees the bobbin-lifter pins 17 and 18 fall. At one hundred and seventythree degrees (173) the bobbiu-levelers 06 and 67 rise, and two degrees, after the carriage being nearly central under the bobbin-box M, the bobbin-supporter B is drawn back, allowing the bobbins to descend and rest upon the bobbin-lifters 17 and 18 and bobbin-levelers 66 and 67. The stop formed by lever S being down prevents the bottom bobbin from being drawn out by the friction. The insertion-studT now rises, and at one hundred and seventy-eight degrees (178) the carriage being now nearly central under the bobbin-box, enters the eye in the bobbin. The stop formed by lever S being lifted at this time, the bottom bobbin is slipped out from under the pile, which is now upheld by the bobbinsupporter R, its pressure having been almost immediately resumed. At two hundred and five degrees (205) the bobbin-levelers 68 and 67 have fallen, and the bobbin-lifters17 and 18 risen so as to bring the bobbin into an inclined position, with its edge opposite the ends of the verge 76, and the roller 79 of the arm 77 then presses upon the bobbin.

Immediately the lateral motion of the insertion-stud T commences, and continues until the insertion is completed, which occupies two hundred and fifteen degrees, (215.) During this operation the bobbin-lifters 17 and 18 are allowed to drop, the pressure of the arm 77 is relieved, and that of arm 78 is ap plied, so as to assist the insertion. The threadearrier C, which at two hundred degrees (200) occupies the position shown in Fig. 2, at two hundred and five degrees (205,) has been advanced to the position shown in Fig. 3, and at two hundred and ten degrees (210) it has laid the thread in the hook 95, (which was lifted just previously, say two degrees.) The hook 95 immediatelysinks, drawing the loop through the thread 99 of the carriage. At about two hundred and twenty degrees (220) the insertion-stud T descends, and at about two hundred and thirty degrees (230) the retractorpin 13 releases the carriage-spring 32. At two hundred and sixty-five degrees (265) the carriage-ejector 110 rises. At two hundred and seventy degrees (27 0) apin of the wheel W engages the bobbin, and removes both it and the carriage from the recess D in the bed, and shortly after delivers it down the chute 118 on to the receiving-belt X. At two hundred and seventy-five degrees (275) the carriage-ejector 110 descends, and the revolution of the bed or disk A is then continued until completed.

It will be understood that each recess in turn receives a carriage from the carriagebox, and that the empty bobbin is removed and delivered into the appropriate receiver L,

a full bobbin inserted, the carriage threaded, and thethreaded carriage with its full bobbin delivered to the carriagereceiver or endless belt X.

If the bobbin-box be not supplied with bob bins, the machine will simply remove the empty bobbins from the carriages, and the mechanism for inserting the bobbins acts idly. On the other hand, if the carriages placed in the carriage-box contain no bobbins, and the bobbin-box be supplied with bobbins, the mechanism for removing the bobbins will operate idly.

A particular and detailed description of the machine shown and its mode of operation has been given for the purpose of showing how the invention is or may be carried into efl'ect, and to enable others to make and use the same; but the invention is not restricted to the precise details, either of construction or of operdent that the supporting device It is applicable to the carriage-box as well as to the bobbinthen parallel therewith to retract the spring,
